OpenVPN could connect but did not ping internal network

I’m setting up my internal infrastructure to use OpenVPN since I want to be able to do a lot of monitoring on the Notiffi system I’m working on and I didn’t want to use an SSH tunnel and I definitely did not want to be sending instrumentation data across the Internet without protection. So I decided to use OpenVPN.

But I had a problem. I was able to connect relatively easily but I could not ping the machines. Routing seemed to be working properly

And it got me wondering if there was just a communication problem due to one side expecting compression and the other side not. In other words, that it wasn’t negotiated. I made the configuration change on BOTH ides this time, tried the ping again and it worked.
